Specification of Letters Patent.

Patented Feb. 19, 1907s Application filed April 4, 1905. RenewedNovember 17.1906. Serial No. 343.930.

To'all whom it may concern:

. .Be itknown that I OLIVER H. P. Con- .iELL, a citizenoftheUnitedStates, residing at Atlanta, in the county of Fulton and State ofGeorgia, have invented certain new and useful Improvements inCotton-Pickers; and I do-hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. a

My invention relates t cotton-pickers or harvesters, has for its objecta machine which can be put 'into operation in a field during'thedifferent stages of maturity of the cotton and ick the rlpened bollswithout disturbingjt letunripe bolls or injuring the plant; and theinvention consists in certain i rovernents in construction which will befully disclosed in. the following specification andclaim's. H, i

In the accompanying drawings, which form part of. this, specification,Figure 1. represents a side elevation of my improved cot- 2, .a verticaltransverse see- Fig. 1; Fig. 3, a top plan a vertical longitudlnalsection on'line 4 4, Fig. 3,-Fig. 5, an enlargeddetail showing one ofthe pickerdisksin plan and its clearing-brush in horiand Fig. 6, a likeview showing two picker-disks and their shaft in elevation, theirseparating-thimbles in section, and theclearing-brush in elevation.

Reference being had to the drawin s and the designating charactersthereon, t ie numeral 1 indicates thefra'ine' of a vehicle on which thecotton-picker is supported; 2, the front axle supported in hangers 3,

m a-m rear wheels, which are connected to the istr'ucture by abifurcated su secured to the frontwheels, and 5 5 the port 6, having aivot 6 at their u per en s, which engage earings 7 to swing aterally toaccommodate themselves to any position er direction in which the vehiclemaytravel; The front wheels are connected to the axle 2 by suitableclutches, as 8, to cause the axle to revolve in unison with the wheels4;.

' Secured to the axle 2 is a graduated spurwheel 9, having a pluralityof toothed members 10-11 12 of different diameters and concentricallyarranged, and on one end of a shaft 13, supported in hangers 14 15 and.in a .teeth are engaged by a gear-wheel upper end of a socketbearing 16,on' the axle 2, is a pinion 17, adjustably secured by a set screw 18 toengage either of the members 1.0, 11, or 12, according to the speed rebe imparted. to the pic cleaningbrushes.

19 is a bevel gear-wheel on the inner end of the shaft 13, which engagesa like wheel 20 on the lower end of a vertical shaft 21, supported on aball-bearing 22, and to whose up er end is secured an externally andinternally toothed gear-wheel 23, whose external 24 on the shaft 25,which supports one of the cleaning-brushes, and which shaft'is supportedon a ball-bearing 26, and the internal teeth are engaged by; agear-wheel 27 on the upper end of a shaft 28, which su ports the othercleaning-brush, and said s iaft is supported on a ball-bearing 29.

30 30 are shafts upon which er-disks and the are mounted olls.

. Cotton, as is well known, begins to ripen or uired or desired. to

mature from the lower end of the-plant upward and requires severalharvestings or pickings to gather all the cotton from the plant. it istherefore very desirable that the upper portion of the plant containingunripe bolls and'blooms .shall not be disturbed or injured in removingthe cotton from the lower or ripened bolls. To accomplish this, thepicker-disks 31 are detachably mounted on the shafts 30, are separatedby thiInbles.

32 between the disks, and secured in position by a claniping-nut 33,which bears upon the thinible above the upper disk.

During the first harvesting or picking'of' cotton the upper picker-disksare removed from the machine to suit the height of the ripened cotton,when sleeves of suitable length are put upon the shafts 30 and the .nuts33 tightened to secure the disks ren1aining on the shafts.

The picker-disks 31 are provided with plain upper and lower surfaces toprevent cotton adhering to them and with a concentrio andinclinedpicking or working surface 34, provided with teeth 35, inclined in thedirection. of revolution of the disks to engage the cotton in theripened and open bolls and remove it therefrom.

The cleaning-brushes are preferably made with heads 36 37, havingp0ckets 38 to receive the separate members 39 hold them. These brushmembers are of the class of brushes used in cotton-gins-end en; gage thepicking-surface 34 of receptacle 40 on the vehicle, from which it isremoved at suitable intervals through door 41 in the rear end of thereceptacle:

The sheftsj30 are supported on bell -besrings 42, and at their upper endare gee!-v wheels43, one of which engages with wheel 2t and the otherwith wheel 27 to revolve the picker-disks 31 at e slower rate of speedthan the cleaning-brushes and in the o posits direction, as indicated byarrows in ig. 3.

M indicates getherers' on the sides of the machine to drew thecotton-plants in tow the picker-disks 31 as the machine is advancing,and between the disks are fingerguerds' t5 to prevent the cotton beingthrown outward awe fromthe receptacle 40 by the r cleaning-bros es.

Having thus fully described my invention, whet I; claim is-- r '1. Acotton-picker having e vertical shaft 'thl'ilgibles b fltwen'seidfdisks; said end I tlhinblesbeingseoured on the shaft by a suitdevice; in combination with revoluble rushes engsging'seid disks to re-;nove cotton therefro i y 2.
